I have asked this many times, including to expert Roy Bishop in Avonport, and nobody seems to know. I'll bet some know-it-all on this list can come up with an/the answer?! My 3-volume Webster's Third Int'l Dictionary says the following: (a) piece of wood used to hold up the front or the tongue of a wagon; (b) "neaped" means left aground by the high water of a spring tide -- ??? Thanks in advance for all attempts, from Jim in Wolfivlle ---------- From: Dusan Soudek <soudekd@ns.sympatico.ca> Reply-To: naturens@chebucto.ns.ca Date: Wed, 02 Aug 2006 21:40:12 -0300 To: naturens@chebucto.ns.ca Subject: Re: [NatureNS] Re: Tides Halifax Harbour Hi all, yes, there can be a huge difference between predicted and actual tides, particularly in tidal rivers and in shallow seas. For example, the Shubie is tidal for some 45-49 km from its mouth. The timing of the so-called tidal bore and the dead high tide depends not only on the size of the tide (neap vs. spring), but on winds, atmospheric pressure, and the amount of flow in the river. This is also true for the St. John River in N.B., where the tides around Fredericton and in Grand Lake (and elsewhere) are discernible only during very low-flow times of the year. Dusan Soudek Paul MacDonald wrote: Hi Blake and All High tides or low ones for that matter have variability based on winds, air pressure and so on so if you were to measure exactly when the highest water was or the lowest - these time measurements would have some noise. Often when out in tidal water you will note the tidal start to fall and then reverse itself and come up some more. The thing is not to get to tied up on exact times.
